Smoking 16hp
 

Hello
New member here.
I'm working on my 1641 in this range of serial # below.

{1641 (145-653-100) - Cub Cadet Garden Tractor (SN: 821060 - 880000) }

When I started It this evening it was really smoking.

Where is the best place to buy parts/ Rebuild kit ?

Thanks in advance for your help.

Model #303447 Type 0447-01 Code 940916

.

I would suggest you take an aspirin and maybe a short nap.

I have owned several 16 hp Vanguards that smoked and none of them required a rebuild. Might be best for you to figure out what is causing the smoke and report back before all the jingle runs out of your pockets?

Thanks.
I will take that advice.
When I purchased it a few weeks ago it was fine.

It is (freshly rebuilt) was the story.

It sounds great.
I will pull the plugs and take a look.
Also Run a compression check.
I will take the muffler off. and check things out .
I will post a picture of the muffler.
It does not look like it is burning good on both cylinders.

Thanks

I run compression test.
150psi even both sides.:Salute:

Right Plug looks normal,
Left Plug Wet. Gas/Oil.

So spark check.
Right side:clap:

Left side:bigthink:

I will look when it gets dark.

I think it has not had spark on this side for a while.

Here is a picture of the Muffler.

Update.
No spark on left side.







.

Update.
The coils check the same Ohm resistance .
The flywheel is rusty.
I will clean this.
I am going to check the gap.
Does anyone have that info?

.

The kill wire that attaches to the coils has diodes in it. I've read that if they go bad it can cause spark failure. I had to replace the one on my 1641 because it got pinched in the shroud.
Cannon

Thank You.

I will check that.







.

The armature air gap is .008-.012.

If you can spin the engine, just remove the kill wire from both armatures and see of both of them spark.

I just replaced a kill wire because of an open diode and one side wouldn't fire.

Some multimeters can check diode function.

I want to Thank both of You.
Mike McKown for slowing me down .:NailBite::NailBite:
And Cannon51 for telling me about the wire.:clap:
And Mike for instruction of leaving the wire off:clap:
It was that wire.
I swapped the coil side to side
Tested everything.
Blah Blah:BlahBlah:
Then left the wire off and (Bam)

Here's a picture

So 2 more Questions.

#1: Where is the best place to buy this wire?

Also there was nothing hooked to it on the outside of the engine.

#2: Does it have to be hooked in the wiring?





.

This is where I got mine.

https://www.amazon.com/Briggs-Stratt.../dp/B005F6P838

Two ends go to the armatures, the single end goes to a spade connector on a stud mounted on the blower housing, right side of the engine inside. Outside, another spade connector the tractor engine harness connects to.

If you don't have the engine harness connected on the outside, you can't ground the armatures to kill the engine.

Thank you for link.

I found wiring schematic on-line
I know there is some on this forum
I'm still learning to navigate the site:biggrin2:

Previous owner had yellow wire attached to fuel solenoid.

Looks like I got some wiring to trace down.

.

They won't run too well like that.:biggrin2:

I am one to share info.
I will try to make things clear when I have this back up to Par.

I have been tracing wires for weeks (when I have time):biggrin2:

I have been working a lot of hours at work.

Here is what I have found in my spare time.

I used the Wiring Diagram for 1641 that is shared on this site.

What I found was Previous owner swaped terminals in the plugs:Huh:

The Ground terminal was in the switch the blue terminal was on ground to switch.

I have got only one more issue to resolve then I will fire it up.







.

Don't ya just love uncovering "cobble jobs"....??? :bash2:

Well, did you get it all straightened out ?

Yes
After I found the bad diode that was pinched in the engine guards
on the 1st page of this thread.

Thanks to help from Cannon51 & Mike McKown

I used the wiring diagram in the link above .

I removed the harness and reconfigured it like it's supposed to be.

The PO had moved wires around in the ignition switch:Shocked:
For what reason:Huh:


It runs like a top now.
